Figure 4. Type CSB400DT Dual Registered Regulator Operational Schematic

Principle of Operation

Type CSB400 Base Regulator Operation

Refer to Figure 4. When downstream demand decreases, the pressure under the regulator diaphragm increases. This pressure overcomes the regulator setting (which is set by the regulator control spring). Through the action of the pusher post assembly, lever and valve stem, the valve disk moves closer to the orifice and reduces gas flow. If demand downstream increases, pressure under the regulator diaphragm decreases. Spring force pushes the pusher post assembly downward, the valve disk moves away from the orifice, and the gas flow increases downstream as the regulator opens in response to the decreased pressure underneath the regulator diaphragm.

Type numbers with a “T”, for example, Type CSB400IT, provide a token or low-capacity relief. The Token relief provides relief from minor overpressure caused by nicks or dents on the orifice or by thermal expansion of gas in the downstream line. Token relief also provides a token or signal, in the form of odor, that an overpressure situation is occurring.

Additional overpressure protection options include Types CSB403 and CSB423, which offer True-Monitor™ protection provided by an integral monitor module installed on the inlet side of the valve body. This Integral True-Monitor assumes control of the pressure to the downstream system should the primary regulator fail to regulate. The Types CSB404, CSB424 and CSB454 are examples of CSB400 Series configurations that offer a slam-shut module that shuts off the flow of gas to the downstream system in the event of outlet pressure rising above or falling below the predefined levels due to a failure.

Optional token relief is available, which acts as a low-capacity internal relief valve to relieve minor overpressure situations due to nicks or other minor damage to the orifice or disk, or due to thermal expansion of the downstream system.

Internal, external or dual outlet pressure registration is available. Constructions with dual or external registration require an external control line / sense line. For quick changing loads, dual sense is recommended as it provides the quickest response time.

Type CSB403 Integral True-Monitor™ OperationType CSB403 combines the operation of a conventional two-regulator wide-open monitor set into one body, see Figure 5. The Integral True-Monitor is installed on the inlet side of the body and serves to throttle flow and maintain an acceptable downstream pressure in the case where the primary regulator ceases to regulate downstream pressure. During normal operation the Integral True-Monitor is in a wide-open state as its setpoint is set higher than the primary regulator. See Table 7 for guidance regarding the setpoints of the regulator and associated Integral True-Monitor sets. If the downstream pressure should rise to the setpoint of the Internal Monitor due to a loss of pressure control by the primary regulator, the Integral True-Monitor will assume control and regulate the flow to the downstream system. If token relief is present, it will relieve a small amount of gas to the atmosphere as an indication that the Integral True-Monitor is controlling the downstream pressure. The Type CSB403 provides the option of internal or external downstream pressure registration. External registration requires a downstream sensing line. See Figure 9 for guidance regarding installation of the downstream control line. Refer to the Type TM600 Instruction Manual for additional details of Integral True-Monitor operation.

Type CSB404 Slam-shut OperationThe Type VSX4 slam-shut module on the Type CSB404 regulator is a fast acting shut-off device that provides overpressure (OPSO) or over and underpressure (OPSO / UPSO) protection by completely shutting off the flow of gas to the downstream system. See Table 8 for guidance regarding the typical setpoints of the regulator and associated slam-shut OPSO and also the combined OPSO and UPSO setpoints. The Type VSX4’s actions are independent of the Type CSB404 regulator and of variations to the inlet pressure. The Type VSX4 comes standard with external downstream pressure registration, with the option for internal registration only on the Rp 1 x 2-1/4 GAZ body. External registration requires a downstream sensing line. See Figure 10 for guidance regarding installation of the downstream control line.

The Type VSX4 shut-off disk is normally in the open (reset) position, see Figure 6. If the downstream pressure below the slam-shut diaphragm increases (or decreases) until it reaches the slam-shut setpoint, this diaphragm moves upward (or downward) to release the trip mechanism which allows the spring force on the stem to push the disk against the seat, shutting off all gas flow. To reset the slam shut after gas has been shut off, refer to the Type VSX4 Instruction Manual for additional details.

In order for the Underpressure Shutoff (UPSO) of any slam shut to be triggered, the downstream pipe pressure must drop below the UPSO setpoint. In the case of a downstream line break, numerous factors can prevent the downstream pipe pressure from decreasing below the slam-shut UPSO setpoint. These factors include the distance of pipe to the break, the diameter of the pipe, size of the break and the number of restrictions, such as valves, elbows and bends, downstream of the regulator and/or slam-shut device. Due to these factors additional protections should be installed to stop flow in the event of a line break.

Installation and Overpressure ProtectionInstall in accordance with provisions of EN 12186 / EN 12279.

! WARNING

Personal injury or system damage may result if this regulator is installed, without appropriate overpressure protection, where service conditions could exceed the limits given in the Specifications section and/or regulator nameplate. Regulator and equipment installation should be adequately protected from physical damage.

All vents should be kept open to permit free flow of gas to the atmosphere. Protect openings against entrance of rain, snow, insects or any other foreign material that may plug the vent or vent line. On outdoor installations, point the spring case vent downward to allow condensate to drain, see Figures 7 through 10. This minimizes the possibility of freezing and of water or other foreign materials entering the vent and interfering with proper operation.

For the Type CSB403 with Integral True-Monitor™ or the Type CSB404 with Slam shut, point the vents of both the primary regulator and Integral True-Monitor or slam shut downward to allow condensate to drain. From the factory, the Integral True-Monitor or slam shut will always point in the same direction as that of the primary regulator.

Under enclosed conditions or indoors, escaping gas may accumulate and be an explosion hazard. In these cases, the vent should be piped away from the regulator to the outdoors.

In case of complete disassembly of the equipment (body included) from the pipeline, care must be taken not to bend, hit or otherwise damage the pitot tube (key 83 Figure 15) that protrudes beyond the body outlet. Damage to the pitot tube could result in inaccurate internal pressure registration and loss of regulation quality.

CAUTION

CSB400 Series regulators have an outlet pressure rating lower than their inlet pressure rating. If actual inlet pressure can exceed the outlet pressure rating, outlet overpressure protection is necessary. However, overpressuring any portion of the regulators beyond the limits in the Specifications section may cause leakage, damage to regulator parts or personal injury due to bursting of pressure-containing parts.

Some type of external overpressure protection should be provided to the CSB400 Series if inlet pressure will be high enough to damage downstream equipment. Common methods of external overpressure protection include relief valves, monitoring regulators, shut-off devices, and series regulation.

If the regulator is exposed to an overpressure condition, it should be inspected for any damage that may have occurred. Regulator operation below the limits specified in the Specifications section and regulator nameplate does not preclude the possibility of damage from external sources or from debris in the pipeline.

Figure 8. Type CSB400 “Series Monitor” Regulator Downstream Control Line Installation

Before installing the regulator, check for damage which might have occurred in shipment. Also check for dirt or foreign matter which may have accumulated in the regulator body or in the pipeline. Apply pipe compound to the external threads of the pipeline and install the regulator so that flow is in the direction of the arrow cast on the body. The diaphragm casing assembly can be rotated to any position relative to the body. Loosen the two cap screws (key 71, Figure 11) in order to rotate the diaphragm casing assembly.

General Installation InstructionsBefore installing the regulator,

• Check for damage, which might have occurred during shipment.

• Check for and remove any dirt or foreign material, which may have accumulated in the regulator body.

• Blow out any debris, dirt or copper sulfate in the copper tubing and the pipeline.

• Apply pipe compound to the external threads of the pipe before installing the regulator.

• Make sure gas flow through the regulator is in the same direction as the arrow on the body. “Inlet” and “Outlet” connections are clearly marked.

• Verify that:- Equipment limits of utilization (PS, TS) corresponds

to the desired operating conditions.- The inlet is protected by an appropriate device(s) to

avoid exceeding the allowable limits (PS, TS).• When designing a pressure reducing station using

a CSB regulator, make an analysis if it is necessary to take into account the effects of wind, snow and temperature to avoid unnecessary load and movement to the flanges of the equipment.

• If needed, a support may be used under the piping and regulator/slam-shut body to avoid excessive pressure force on the regulator/slam shut.

Installation Location • The installed regulator should be adequately

protected from vehicular traffic and damage from other external sources.

• Install the regulator with the vent pointed vertically down, see Figures 7 through 10. If the vent cannot be installed in a vertically down position, the regulator must be installed under a separate protective cover. Installing the regulator with the vent down allows condensation to drain, minimizes the entry of water or other debris from entering the vent, and minimizes vent blockage from freezing precipitation.

• Do not install the regulator in a location where there can be excessive water accumulation or ice formation, such as directly beneath a downspout, gutter or roof line of building. Even a protective hood may not provide adequate protection in these instances.

• Install the regulator so that any gas discharge through the vent or vent assembly is over 0.91 m / 3 feet away from any building opening.

Regulators Subjected to Heavy Snow ConditionsSome installations, such as in areas with heavy snowfall, may require a hood or enclosure to protect the regulator from snow load and vent freeze over.

Downstream Control Line Installation

! WARNING

Failure to install a downstream control line could result in a hazardous condition. Install downstream control line(s) to the slam-shut device when construction uses external pressure registration.

The regulator and slam-shut device will not control pressure or shutoff if a downstream control line is not installed on those constructions where external pressure registration is required.

CSB400 Series regulators with an “ET” or “EN” in the type number use external pressure registration. To communicate the downstream pressure to the regulator, connect a downstream control line tubing to the 3/4 NPT control line tapping in the lower diaphragm casing and connect the other end of the tubing downstream of the regulator outlet with a minimum distance of 4 times the outlet pipe diameter.

For Types CSB400 and CSB404 with external control lines, use tubing with an outer diameter of 9.5 mm / 0.375 inch or larger. For Types CSB420, CSB424, CSB450 and CSB454 with external control lines, use tubing with an outer diameter of 13 mm / 0.5 inch or larger.

The Types CSB410, CSB414, CSB430 and CSB434 are dedicated wide-open monitoring regulators and are installed upstream of a primary working regulator. Refer to Figure 8 for installation of the downstream control line. To communicate the downstream pressure to the wide-open monitor regulator, connect a downstream control line tubing to the 3/4 NPT control line tapping in the lower diaphragm casing of the monitor regulator and connect the other end of the tubing downstream of the regulator outlet with a minimum distance of 4 times the outlet pipe diameter.

For Types CSB410 and CSB414, use tubing with an outer diameter of 9.5 mm / 0.375 inch or larger.

For Types CSB430 and CSB434, use tubing with an outer diameter of 13 mm / 0.5 inch or larger.

Downstream Control Line Installation with Integral True-Monitor™

Refer to Figure 9. When installing the Types CSB403 and CSB423 regulators, connect downstream control line tubing to the lower casing of the primary regulator, and run the tubing downstream of the regulator outlet with a minimum distance of 4 times the outlet pipe diameter. Connect a second, separate downstream control line tubing to the lower casing of the Integral True-Monitor, and run the tubing downstream of the regulator outlet with a minimum distance of 4 times the outlet pipe diameter. For Type CSB403 with external control lines, use tubing with an outer diameter of 9.5 mm / 0.375 inch or larger for both the primary regulator and Integral True-Monitor.

CSB400 Series

15

For Type CSB423 with external control lines, use tubing with an outer diameter of 13 mm / 0.5 inch or larger for both the primary regulator and Integral True-Monitor™.

Downstream Control Line Installation with Slam shutRefer to Figure 10. When installing the Types CS404ET, CS404EN, CSB424ET, CSB424EN and CSB454EN regulators, connect downstream control line tubing to the lower casing of the regulator and run the tubing downstream of the regulator outlet with a minimum distance of 4 times the outlet pipe diameter. Connect a second, separate downstream control line tubing to the lower casing of the slam shut and run the tubing downstream of the regulator outlet a minimum distance of 4 times the outlet pipe diameter.

For Type CSB404 with external control lines, use tubing with an outer diameter of 9.5 mm / 0.375 inch or larger for the primary regulator and 6.4 mm / 0.25 inch or larger for the slam shut.

For Types CSB424 and CSB454 with external control lines, use tubing with an outer diameter of 13 mm / 0.5 inch or larger for the primary regulator and 6.4 mm / 0.25 inch or larger for the slam shut.

Installation with External Overpressure ProtectionIf the regulator is used in conjunction with a Type 289H relief valve, it should be installed as shown in Figure 7. The outside end of the vent line should be protected with a rainproof assembly. The Type 289H is typically set 25 mbar / 10 inches w.c. higher than the outlet pressure setting of the regulator, up to 75 mbar / 30 inches w.c. outlet pressure. For pressure greater than this, set the Type 289H 0.05 bar / 0.75 psi higher than the outlet pressure setting of the regulator.

Vent Line InstallationThe CSB400 Series regulators have a 1 NPT screened vent opening in the spring case. If necessary to vent escaping gas away from the regulator, install a remote vent line in the spring case tapping. Vent piping should be as short and direct as possible with a minimum number of bends and elbows. The remote vent line should have the largest practical diameter. Vent piping on regulators with token relief must be large enough

to vent all relief valve discharge to atmosphere without excessive backpressure and resulting excessive pressure in the regulator.

For types with optional Token relief, this low capacity relief is located in the spring case of the primary regulator. If necessary to vent escaping gas away, install a remote vent line in the spring case tapping of the primary regulator as described above. Periodically check all vent openings to be sure that they are not plugged or obstructed.

CSB400 Series outlet pressure ranges are shown in Table 6. Outlet pressure higher than 0.34 bar / 5 psig above the setpoint may damage internal parts such as the diaphragm head and valve disk. The maximum emergency (casing) outlet pressure is 4.0 bar / 58 psig.

Commissioning

CAUTION

Pressure gauges must always be used to monitor downstream pressure during Startup.

With the downstream system depressurized, use the following procedure to start up the regulator.1. Check to see that all appliances are turned off.2. Slowly open the upstream shut-off valve. 3. Check inlet and outlet pressure for correct values. 4. Check all connections for leaks. 5. Turn on utilization equipment and recheck

the pressures.

AdjustmentNote

For types that include the Integral True-Monitor module, refer to the Instruction Manual for Type TM600 Integral True-Monitor for adjustment and maintenance of the Integral True-Monitor. For the types that include the slam-shut module, refer to the Instruction Manual for Type VSX4 slam shut for adjustment and maintenance of the slam shut.

CSB400 Series

16

The range of allowable pressure settings for the primary regulator is stamped on the nameplate. If the required setting is not within this range, substitute the correct spring (as shown in Table 6). If the spring is changed, re-stamp the nameplate to indicate the new pressure range.

A pressure gauge must always be used to monitor downstream pressure while adjustments are being made.

For Types CSB400 and CSB4201. Remove the closing cap (key 60, Figure 16). 2. To increase the outlet setting, turn the adjusting

screw (key 65) clockwise. To decrease the outlet setting, turn the adjusting screw counterclockwise.

3. Replace the closing cap.

For Type CSB4501. Loosen the hex nut (key 58, Figure 16). 2. To increase the outlet setting, turn the adjusting screw

(key 65, Figure 16) clockwise. To decrease the outlet setting, turn the adjusting screw counterclockwise.

3. Tighten the hex nut.

CSB400 Series with Integral True-Monitor™When adjusting the primary regulator and Integral True-Monitor for operation, ensure that the pressure differences between the primary regulator and the integral monitor shown in Table 7 are observed. For example, if the primary regulator setpoint is set at 20 mbar / 8 inches w.c., then the Integral True-Monitor should be set at a minimum of 35 mbar / 14 inches w.c. or higher.

To test the Integral True-Monitor operation, the primary regulator setpoint must be adjusted above the Integral True-Monitor’s setpoint to simulate a failure of the primary regulator. If the spring range of the primary regulator is sufficiently high, it can simply be adjusted above the Integral True-Monitor’s setpoint by following step 2 above. Otherwise, a different spring with a setpoint higher than the Integral True-Monitor’s setpoint must be installed to check the operation of the Integral True-Monitor.

CSB400 Series with Slam shutWhen adjusting the primary regulator and slam shut for operation, refer to Table 8 for the OPSO setpoints and also the combined OPSO and UPSO setpoints of the slam shut for a given regulator spring ranges.

CAUTION

Equipment installed downstream the Type VSX slam shut device can be damaged if the following procedure for resetting the Type VSX slam shut device is not followed. This equipment includes the integral Type VSX or regulator configurations.

Step 1: • To properly reset the Type VSX slam shut after it

has been tripped to the closed position, a flat-head screwdriver must be inserted into the position shown in Figure 8 on the backside of the reset button (refer to Type VSX4 Instruction Manual, key 30, Figure 8).

Step 2: • The screwdriver should be slowly rotated to gradually

pull the reset button (refer to Type VSX4 Instruction Manual, key 30) away from the Type VSX device. This slow movement allows for a slow bleed of the pressure across the Type VSX slam shut’s disk and seat area. The operator should be able to hear the pressure bleeding through the system.

Step 3: • When the pressure has equalized and the air

bleeding sound has dissipated, the reset button (refer to Type VSX4 Instruction Manual, key 30) should be pulled completely away from the Type VSX slam shut device by hand until the internal shut-off mechanism has been re-latched.

Step 4: • Once the operator feels the click of the re-latch

occurring, the reset button (refer to Type VSX4 Instruction Manual, key 30) should be pushed completely back into its original position.

! WARNING

In the case of a downstream line break, numerous factors affect the capability to evacuate gas from the pipeline. These factors include the distance of pipe to the break, the diameter of the pipe, size of the break and the number of restrictions, such as valves, elbows and bends, downstream of the regulator and/or slam-shut device. Due to these factors additional protections should be installed to stop flow in the event of a line break.

ShutdownInstallation arrangements may vary, but in any installation it is important that the valves be opened or closed slowly and that the outlet pressure be vented before venting inlet pressure to prevent damage caused by reverse pressurization of the regulator. The following steps apply to the typical installation as indicated.

1. Open valves downstream of the regulator.2. Slowly close the upstream shut-off valve.3. Inlet pressure should automatically be released

downstream as the regulator opens in response to the lowered pressure underside of the diaphragm.

4. Close outlet shut-off valve.

Maintenance and Inspection

! WARNING

To avoid personal injury or equipment damage, do not attempt any maintenance or disassembly without first isolating the regulator from system pressure and relieving all internal pressure as described in “Shutdown”.

Regulators that have been disassembled for repair must be tested for proper operation before being returned to service. Only parts manufactured by Regulator Technologies should be used for repairing Fisher® regulators. Restart gas utilization equipment according to normal startup procedures.

Due to normal wear or damage that may occur from external sources, this regulator should be inspected and maintained periodically. The frequency of inspection and replacement depends on the severity of service conditions, test results found during the annual test, and on applicable codes and regulations. In accordance with applicable National or Industry codes, standards and regulations/recommendations, all hazards covered by specific tests after final assembly, before applying the CE marking, shall also be covered after every subsequent reassembly at installation site in order to ensure that the equipment will be safe throughout its intended life.

Periodic inspection must be performed on the CSB400 Series that include the Integral True-Monitor™ or slam-shut overpressure protection modules to ensure that they protect the downstream system in the event the primary regulator losses pressure control. This inspection must test that the Integral True-Monitor or slam-shut functions as intended.

NoteFor adjusting setpoints above 100 mbar / 1.5 psig, use a 13 mm / 1/2-inch hex driver, a 13 mm / 1/2-inch socket or a 27 mm / 1-1/16-inch socket to turn the adjusting screw (key 65).

Disassembly to Replace the Regulator Main Diaphragm1. Remove the closing cap (key 60, Figure 11) or loosen

hex locknut (key 58, Figure 16). Turn the adjusting screw (key 65) or nut (key 58) counterclockwise to ease spring (key 38) compression.

2. Remove the adjusting screw (key 65) and spring (key 38).

3. Remove hex nuts (key 16, Figure 11) and cap screws (key 15, Figure 11). Separate the upper spring case (key 1) from the lower casing assembly (key 9).

Note

When disassembling a CSB400 Series regulator, lift the upper spring case (key 1) straight up in order to avoid hitting the stem (key 44).

4. Slide the diaphragm assembly (key 55) away from the body (key 70) to unhook the pusher post (key 51) from the lever (key 10). Lift off the diaphragm assembly (key 55).

5. a. For none relieving units such as the Types CSB400IN and CSB400EN, unscrew the cap (key 45), see Figure 12, high-pressure Non-Relief and low-pressure Non-Relief assemblies. The cap fastens the R.V. spring seat (key 43) to the pusher post (key 51). Unscrew the cap to separate the R.V. spring seat (key 43), diaphragm assembly (key 55) and pusher post (key 51).

b. For units with internal token relief such as Type CSB400IT, refer to Figure 12, unscrew the adjusting upper seat (key 47). This will allow for removal of the relief spring (key 41), R.V. spring seat (key 43), diaphragm assembly (key 55) and pusher post (key 51).

6. Reassemble the spring case (key 1) unit in the reverse order of the above steps. Before tightening the cap screws (key 15) or stem (key 44) into the pusher post (key 51), place the loosely-assembled diaphragm assembly (key 55) into position in the lower casing (key 9), being sure that the pusher post (key 51) is hooked on the lever (key 10). Rotate the diaphragm (key 55A) so that the diaphragm and lower casing (key 9) holes are aligned. Tighten the stem (key 44) or diaphragm retainer (key 45) for HP and LP non-relief assemblies.

Disassembly to Replace Valve Disk, Balanced Port Assembly Diaphragm and Regulator Orifice

1. Remove the bolts (key 71, Figure 11) which hold the lower spring casing (key 9) to the body (key 70). Separate the lower spring casing (key 9) from the body (key 70).

2. Check the body O-ring (key 21) for wear. 3. Remove the balanced port assembly (key 35,

Figures 11 and 13) from the body, make sure to rotate the assembly toward the outlet of the body as it is being removed to clear the sense tube from the body.

4. Examine the valve disk (key 35K) for nicks, cuts and other damage. If damage is present, it is recommended to replace both the disk and also the balanced port diaphragm (key 35F) and associated diaphragm O-ring (key 35M), that comes into direct contact with the inner flange of the balanced port diaphragm. Start the process of replacing the disk by disassembling the balanced port assembly. Remove the four cap screws (key 35R) and then the cap (key 35G).

5. Grasp the spring retainer (key 35C) and slide the brazed housing (key 35A) away to expose the diaphragm (key 35F) and disk (key 35K). Still grasping the spring retainer (key 35C) insert a 5 mm Allen wrench into the disk screw (key 35E) and unscrew.

6. Remove the disk (key 35K) and discard if damaged Slide the diaphragm O-ring (key 35M) off the stem (key 35B) along with the diaphragm (key 35F). Slide the new diaphragm over the stem in the same manner that it was removed, make sure that it completely contacts the surface of the inner retainer (key 35J).

7. Reassemble the Balanced Port assembly in reverse order of the above. Ensure Dow Corning® 33 or comparable extreme low temperature lubricant completely coats the O-ring (key 35M), stem (key 35B) and the center bore of the outer retainer (key 35H).

8. Examine the seating edge of the orifice (key 25). If it is nicked or rough, replace the orifice and O-ring (key 27). If a slam shut or monitor is installed on the backside of the body, refer to the applicable Instruction Manual for inspection and removal of the overpressure protection orifice (key 26) and O-ring (key 27).

9. Reassemble the regulator in reverse order of the above steps.

Regulator ReassemblyAs indicated by the square callouts in Figures 11 to 17, it is recommended that a good quality pipe thread sealant be applied to pressure connections and fittings and a good quality extreme low temperature lubricant, such as Dow Corning® 33, be applied to O-rings. Also apply an anti-seize compound to the adjusting screw threads, orifice threads and other noted areas as needed.
